To all whom it may concern: 1

Be it known that I, FRITZ BAUM, a citizen of the Republic ofSwitzerland, residing at. Rorschach, Switzerland, have invented certainnew and useful Improyements in Auto- 1 matic lVinding-Frames; and I dohereby de- 4 clare the following to be a full, clear, and exactdescription of the invention, such .as

will enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying ofthe windin ofthe next one, in such a way that, on the finished wound pirn or cop theordinary central binding is produced and for the next pirn or cop to bewound a foundation is wound serving as the core for the pirn or co Theobjectof the latter winding is to enab e the thread, when the pirn orcop is unwound, to be drawn off uniformly from the conunencemerit to theend and thereby to avoid the thread breaking, such as takes place inmachines with pirns or cops made on frames the thread guides of whichhave a constant movement, the foundation of the pirn or cop not beingwound regularly but merely in an irregular confusion. This winding framealso consists in an arrangement by which the pirn or cop tube isrendered stationary by its being pushed forward by means of a deviceacting against the rear end of the pirn or cop tube shaft.

A form of construction of the objects of the invention is shown as anexample in the accompanying drawings, in which,

frame. This has two iongitudinally dis placeable pirn or cop tube shafts1 arranged parallel to one another and lying near together, which shaftscarry the tubes 2 on The drawings show a double winding rear ends ofthepirn tu e shafts.

which the pirns or cops are wound; also thread guides 3 which lay thethreads in coils; feelers 4, which on the desired thickness of the pirnor cop being obtained couple up a mechanism which influences the threadguides, so that the foundations are laid round the pirns or cops andafter the finished pirns or cops have been displaced to the ends of thepirn or cop tubes by dofl 'ers or scraping off devices 5 operated bythis mebhanism, foundations are wound'on the pirn or cop tubes for thefresh pirn or cops to be wound. a

The means for operating the above mentioned main parts will now behereinafter described. The pirn tube shafts are operated from the maindriving shaft 6. For this ob- 'ect on the pirn tube shafts looselyrevoluble ut undisplaceably arranged toothed wheels 7 are mounted inengagement with a toothed wheel 8 mounted on the main driving shaft, andfor each pirn tube shaft a releasable key coupling is provided betweensaid shafts and the toothed wheels looselyrevolubly mounted on them. Ofthese con lings the one for the left hand pirn tube shaft is shown inthe drawings. -This coupling consistsof a pin 9 (Fig. 2) inserted in thehub of the toothed wheel 7 arranged on the shaft, a sleeve 10 with arecess or notch 11 on the shaft and a spiral spring 12. Now at themomentat which a pirn is to be drawn off, the coupling of the pun tubeshaft on -which the pirn is mounted, is disengaged. This is effected bypushing forward this pirn tube shaft, wherey the pin 9 of the toothedwheel arranged thereon escapes'f'rom the notch 11 and the toothed wheelturns loosely on the shaft. Cam disks'16 are arranged on an auxiliaryshaft 15 operated by a worm ear 13, 14, from the main driving shaft ofthe machine, for this ushing'forward of the pirn tube shafts, w rich camdisks act on upright levers 17 by the intermediary of rollers 19 (Fi s.1 and 6) bearin a ainst the periphery of t 1e cam disks 16, w ic leversare ivoted on the bed late or foundation 18 o the machine and ear withtheir up er ends against the disks havea raised. art 16 which, as ,soonas it acts on the T0 er 1}) ofthe respective lever 17, pushes the pirntube shaft forward. while as soon as the raised parts of the cam diskspass the rollers the spiral springs 12 of The cam SWITZERLAND, ASSIGNORTO THE FIRM OF FRITZ BAUM 6: 00., OF R-ORSCHACH, SWITZERLAND.

- notches 32, as may be seen in the the coupling hereinbefore described,push by the intermediary of support pieces 48; -The supporting piecesare pivotally mounted in the arms 24 on bolts 48 (Fig. 3). Beneath thesesupport pieces notc es 25 are provided on the arms 24', into whichnotches the lower arms of the thread guides may be drawn by means ofspiral springs 26 engaging thereon. (Fig. 3 shows the thread guide ofthe right hand irn tube shaft in this position). When the t read guide 3is in notch 25, as shown at the right of Fig. 3, arm 24 and thread guide3 are rigidly locked together, and the eye in the thread guideoscillates in a long are whose center is that of shaft 23, but when theguide 3 is disenga ed from notch 25 and enters notch 27 the thread guideand its sup orting piece 48 is free to turn with bolt 48 however, the uper end of the guide is held in notch 27 whic 1 acts as a fulcrum, sothat the eye of the thread guide will describe a much shorter arc ofoscillation whose center is the notch 27 At the level of the upper endiece of each thread guide, a horizontal fixed plate 27 is arranged onthe arm 24, on the opposite side of the thread guide to the pirn tu e,which plate has at the edge next to the thread guide a notch or slot 27X (Figs. 2 and 8). Into these notches the u per end parts of the threadguides may e moved by means of arms 28 double armed levers 28, 29,mounted on the bed-plate and adapted to pivot horizontally (Fig. 3 showsthe thread guide of the left hand pirn shaft in this condition); theother arm 29 of this lever lies within reach of the arm 30 ofdouble-armed levers 30, 31, also mounted on the bed-plate and adapted toivot horizontally. The other arms 31 of t ese levers lie Within reach ofthe action of cam disks 32 .Which. are loosely revolubly arranged on anauxiliary shaft 15 and form one piece with the cam disks 16; these camdisks 32 have a projecting part 32 (Figs. 2 and 7) and a notch 32* theyform the one (loosely revoluble) half of clutch couplings 33 arranged onthe auxiliary shaft. Rollers 34 fixed near to the cam disks 32 may dropinto the ower part of Fig. 2. 35 are springs which tend to keep thehalves of the couplings 33 apart.

Now when a co or pirn has been wound to the desired thic ess, the clutchcoupling 33 belonging to the shaft of the tubeon which this pirn iswound is brought into action in a manner hereinafter described by meansof the feeler. By this means the disks 32 and 16 forming one piece withone half of this clutch coupling are turnedby the auxiliary shaft andthe raised part 32 of the disk 32 acts on the respective arm 31, wherebythe levers 30, 31 and 28, 29 are displaced (Fig. 7) and the arm 28 movesthe thread guide belonging to the before mentioned pirn tube shaft intothe slot 27 of'the plate 27 belonging to this thread guide (Fig. 2 aboveand Fig. 3 left hand side). The ower arm of the thread guide is therebydrawn out of the notch 25 of the arm 24 carrying the thread guide. Inthis position of the thread guide it no longer makes the full movementwith the arm 24, by which the thread guide was previously swung out tothe entire length of the pirn or cop, but only makes a small movement,its u per part being retained or held by the p ate 27, so that thethread guide can only swing on this caught part; it is also carriedalong with the support piece 48, the pin 48 of which turns to and fro inthe arm 24. This comparatively small movement of the thread guide causesthe central winding of the pirn and later, after the finished pirn hasbeen suitably displaced to the 'end of the irn tube by the doffer 46,the winding of t e foundation for the new pirn which is to be wound(Fig. 8). When the arm 31 is released from the projecting part 32*, thelevers 30, 31, and 28, 29., return to their former position by theaction of the spring 49 and the thread guide is caused, by the spring 26to disengagefrom the notch 27 X of the plate 27 and to be again coupledwith the arm 24. The cam disk 32 turns farther until its notch 32 facesthe roller 34. At this moment, by means of the spring 35 belonging tothe respective clutch couplin the half coupling which is displaceab eand revoluble on the auxiliary shaft is pushed back into its initialposition, in which it is secured by the engagement of the roller 34 inthe notch 32; during the turning of'the cam disk the roller 34 insuresthe engagement of the coupling by bearing against the back of the camdisk.

The engagement of the couplings arranged on the auxiliary shaft isoperated from the feelers 4. These form one arm of double armed leverspivotal on horizontal axes, the other arm 36 (Fig. 5) of which has at 36a sprin hinge and extends laterally to near the isks 16. For each ofthese double armed levers an inclined plane 37 (Figs. 4 and 5) isprovided against which the arms 36 bear. Durin the winding the feelerwhich bears from ieneath against the pirn is pressed downward by theincreasing size of the latter, the arms 36 being movedupward on theinclined plane, the consequence of '1'0 sition by springs 38.

The doub e armed levers forming thefeelers are, after the removal of the pirns, again returned to theirinitial po- The operation of removing the irns takes place again fromthe auxiliary s aft. For this. object slide projections 39 (seeparticularly Fig. 6) aremounted on the cam disks 1 5 16, whichprojections act in conjunction with vertical draw-bars 40; these areguided at their lower parts by means of pins passing through uldes andhave projections 41 against w ich the slide projections 39 strike endsof the drawbars 40 are connected with one arm 42 of elbow levers, theother arms 43 of which are forked. With these forks the arms 43 engagems 44, which are supported by pieces 45 an carried by bars 46 arrangedover the pirn tube shafts and displaceable in their directions. Thesebars have at their front ends doifers 5. For operating the doffers forthe purpose of doffing the pirns, the slide projections 39 rotating withthe disks 16 encounter the projections 41 and draw the drawbars 40downward, while gradually slipping .611? the projections. The elbowlevers 42, 43, are thereby dis laced and by means of the parts 44, 45,the ars 46 together with the doffers 5, are pushed forward, whereby thepirns are dofied. When this has-been done, the projections 39 slip downfrom the projections 41, whereupon the rails together with the doflersare again returned by the springs 47. Q As the separate parts of thisimproved winding machine have been hereinbefore I described as regardstheir form and method of working, this machine will now be furtherdescribed in conjunction with a continuous method ofworkingl.
